Title: I Can Determine The Height Of A Rocket!
Description:
The lesson is intended to give students a fun real-world experience in applying their math skills. They will use trigonometric ratios to calculate heights of tall structures. They will also use the Internet to convert their calculations from standard to metric units and visa versa.
Standard(s): [MA2013] GEO (9-12) 39: Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).* [G-MG1]

Title: How tall is the school's flagpole?
Description:
The purpose of this lesson is to help students apply math concepts concerning similar triangles and trigonometric functions to real life situations. The students learn how to take these concepts and use them to find measurements of objects that they are unable to measure in conventional ways.

Title: Turtle Pond
Description:
In this student interactive, from Illuminations, students guide a turtle to a pond using computer commands. They improve their skills in estimating length and angle measurement as they enter a sequence of commands (distances and angles at which to turn) to help the turtle move toward the pond. The goal is to find the shortest path to the pond.
Standard(s): [MA2013] GEO (9-12) 19: Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle leading to definitions of trigonometric ratios for acute angles. [G-SRT6]
